Filter by:The disease caused by the pathogen SARS-CoV-2 is known as coronavirus disease with the acronym COVID-19. The acute phase of this condition typically lasts one to two weeks and usually results in a full recovery. However, in about 10-30% of those affected, the symptoms persist for more than four weeks after the onset of the disease. In this case, there is an ongoing COVID-19 illness known as long COVID. Long COVID can persist for many months and cause significant distress and limitations to those affected due to the long-term health consequences. The causes of long COVID are still unclear and, accordingly, therapeutic measures are still insufficiently developed. It is assumed that long COVID can in principle affect anyone. Age, gender, obesity and the number of symptoms during an acute COVID-19 illness are discussed as risk factors for long COVID. Another potential risk factor for developing long COVID could be chronic stress, which has been shown to put a strain on the immune system. It is known from infections with other coronaviruses and other viral respiratory diseases that chronic stress can lead to prolonged illness and limited recovery. The aim of this study is to systematically examine chronic stress, as it existed before infection with the coronavirus, as a possible risk factor for long COVID. For this purpose, 600 people who have been proven to be infected with SARS-CoV-2 and have developed symptoms of COVID-19 will be included in this study.
The Grand Est region is one of the most affected regions in France during the first wave of the COVID-19 epidemic. A significant increase in the number of patients hospitalized for SARS-CoV 2 infection at the University Hospitals of Strasbourg (HUS) led to a sudden saturation of their capacities. Hospital workers appear to be a population at particular risk for this new infectious agent. The percentage of hospital workers who have been in contact with the virus or have contracted COVID-19 is unknown. The objective of this work is to determine the prevalence of SARS-CoV-2 positive serologies among hospital staff screened from June 22, 2020 to November 1, 2020 following a screening campaign offering serological testing to all volunteer HUS professionals.
This study is a randomized, double-blind, placebo-controlled Phase II clinical trial to evaluate the safety and immunogenicity of SCTV01E in population of different ages who have been vaccinated against COVID-19. A total of 750 participants ≥3 years old who have received the recommended dose and immunization procedure of domestically approved COVID-19 vaccines will be enrolled, including 250 participants ≥18 years old (group A), 250 participants aged 12-17 years old (group B), and 250 participants aged 3-11 years old (group C). The study will be carried out gradually according to the age of the participants from older to younger. Considering that SCTV01E in this study is the first clinical study in participants under 18 years old, 15 sentinel participants will be assigned to group B and 30 sentinel participants will be assigned to group C (including 15 aged 6-11 years old and 15 aged 3-5 years old). The Primary end points are 1. The incidence and severity of solicited adverse events on days 0-7 after inoculation with SCTV01E. 2. IgG total antibody concentrations (ELISA) against SARS-CoV-2 prototype strains and neutralizing antibodies titer (Live virus neutraliztion antibody test) against SARS-CoV-2 Omicron variant at 28 days post-vaccination.
This is a future-proof and randomized controlled clinical study on the clinical efficacy of graphene photothermal adjuvant therapy in Corona Virus Disease 2019(COVID-19) patients with mild symptoms. The objective is to examine the effect of graphene photothermal adjuvant therapy on the time line for such Corona Virus Disease 2019 patients to achieve a negative severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) nucleic acid test result, and their duration of disease. Patients who meet study criteria will be randomized into the Grapheme adjuvant therapy combined with conventional therapy group (treatment group) and the conventional therapy only group (control group). Contrasted to the control groups, the treatment groups will undergo 30-min of graphene adjuvant therapy every day for 7 d.
This study aims to compare epidemiology, management of invasive ventilation and outcomes in critically ill patients with COVID-19 ARDS and ARDS from another pulmonary infection. The investigators will use individual patient data from four recently published large observational COVID-9 studies, including the 'Practice of VENTilation in COVID-19 patients' (PRoVENT-COVID) study, the 'Epidemiology of COVID-19 patients in the ICU' (EPICCoV) study, the 'SATI-COVID-19 - Clinical Characteristics and Outcomes of Patients With COVID-19 on Mechanical Ventilation in Argentina: a Prospective, Multicenter Cohort Study' and the CIBERESUCICOVID - Personalized Risk and Prognosis Factors and Follow-up at One Year of the Patients Hospitalized in the Spanish Intensive Care Units Infected with COVID -19' study. The investigators will use the individual patient data from ARDS patients with another pulmonary infection from the 'LUNG -SAFE - Large Observational Study to UNderstand the Global Impact of Severe Acute Respiratory FailurE' study and the 'ERICC - Epidemiology of Respiratory Insufficiency in Critical Care' study.
It is aimed to reveal the treatment and prognostic values by evaluating the differences in hematological parameters and indices, especially in dead Covid-19 cases. Material Method: It is planned to retrospectively examine the hemogram parameters of 125 male, 44 female and 169 critical Covid-19 patients hospitalized between 01.03.2020 and 31.12.2021. Subjects were divided into 2 groups as deceased (77) and living (92) patients according to demographic data such as age and gender. Statistical evaluation: All analyzes were SPSS 25.0, Kolmogorov Smirnov test was used to determine distribution, median and interquartile range (Tukey's Hinges Percentile) were used to summarize variables. The differences between the Independent-Samples Mann Whitney U Test and the data of the patient groups and the optimal cut-off values, sensitivity and specificity values will be determined by ROC analysis. It will be considered statistically significant when the p value is below 0.05 (with the two-tailed test)
The Study objective is to measure retinal neurovascular coupling and blood flow parameters in patients previously infected with COVID-19, long COVID-19 and healthy age- and sex- matched control subjects
In this study we aim to evaluate the radiological and functional changes in post-acute covid-19 pulmonary fibrosis patients in relation to anti-inflammatory and/or antifibrotic drugs prescribed during and after covid-19 pneumonia.
The goal of this clinical trial is to learn about the effectiveness of supportive psychotherapy in post covid-19 syndrome patients. The main questions it aims to answer are: 1. What is the effect of supportive psychotherapy on psychological and somatic symptoms in post covid-19 syndrome patients? 2. What is the effect of supportive psychotherapy on the neutrophil lymphocyte ratio in post covid-19 syndrome patients? 3. What is the effect of supportive psychotherapy on heart rate variability in post covid-19 syndrome patients? Participants will be given supportive psychotherapy in the form of an online group for 3 times a week with a duration of psychotherapy ranging from 1 - 2 hours per session. Researchers will compare the supportive psychotherapy group to education group as control. The control group will be given education about Post Covid-19 syndrome in the form of an online group for 3 times a week with a duration of around 1 - 2 hours per session.
AZD3152, a single mAb, is being developed to have broad neutralizing activity across known SARS-CoV-2 variants of concern for pre-exposure prophylaxis of COVID-19. The aim of the Phase I/III study (Parent Study) will be to evaluate the safety, efficacy and neutralizing activity of AZD3152 compared with comparator for pre exposure prophylaxis of COVID-19, and separately evaluate the safety and PK of AZD5156, a combination of AZD3152 and AZD1061. Sub-study: This Phase II sub-study of SUPERNOVA will assess the safety, PK, and predicted neutralizing activity of AZD3152 compared with EVUSHELD for pre-exposure prophylaxis of COVID-19.
